Steps to reproduce

I have successfully installed xgboost and it is shown at the root. However, when i tried to import xgboost it said the package is not there.

OSError: dlopen(//anaconda/lib/python2.7/site-packages/libxgboostwrapper.so, 6): Library not loaded: @rpath/./libgomp.1.dylib
Referenced from: //anaconda/lib/python2.7/site-packages/libxgboostwrapper.so
Reason: image not found

@ghostintheshellarise the version xgboost=0.3 seems very outdated. since you have conda, do you want to try pip install xgboost ?

[ghostintheshellarise]

I following this instruction

1. Open Terminal
2. type : git clone https://github.com/dmlc/xgboost.git
3. type : cd xgboost; make; cd wrapper; python setup.py install --user

But it doesn't work at the last command
python setup.py install --user

and return following error message

Traceback (most recent call last):
  File "setup.py", line 19, in <module>
    LIB_PATH = libpath['find_lib_path']()
  File "xgboost/libpath.py", line 47, in find_lib_path
    'List of candidates:\n' + ('\n'.join(dll_path)))
__builtin__.XGBoostLibraryNotFound: Cannot find XGBoost Libarary in the candidate path, did you install compilers and run build.sh in root path?

/Users/SimonTse/xgboost/python-package/xgboost/./lib/libxgboost.so
//anaconda/xgboost/libxgboost.so

And I did try to install via pip instruction but it gave me the message that I am already installed with xgboost

Requirement already satisfied (use --upgrade to upgrade): xgboost in /anaconda/lib/python2.7/site-packages

I am no CS trained so everything looks so cryptic to me

I am experiencing the same issue:

Cannot find XGBoost Libarary in the candidate path, did you install compilers and run build.sh in root path?

Did you find any solution?

Thank you very much :)

@felipecruz91 have you tried with pip install xgboost after having necessary compilers (gcc 5 for example), instead of using conda install?

[felipecruz91]

@phunterlau Yes I tried using pip install xgboost but I get the following error:

No files/directories in C:\Users\....\AppData\Local\Temp\pip-build-9j_99ys4\xgboost\pip-egg-info (from PKG-INFO)

[phunterlau]

Oh, you use windows, please install from GitHub

[felipecruz91]

@phunterlau I tried installing from Github:

git clone --recursive https://github.com/dmlc/xgboost
git submodule init
git submodule update
alias make='mingw32-make'
cp make/mingw64.mk config.mk; make -j4
cd python-package
python setup.py install

And I get the following error:

Traceback (most recent call last): File "setup.py", line 19, in <module> LIB_PATH = libpath['find_lib_path']() File "xgboost/libpath.py", line 46, in find_lib_path 'List of candidates:\n' + ('\n'.join(dll_path))) XGBoostLibraryNotFound: Cannot find XGBoost Library in the candidate path, did you install compilers and run build.sh in root path?

Any idea?

Thank you very much :)

@felipecruz91 please follow this instruction by IBM (as mentioned in the installation instruction too) , step by step, strictly
https://www.ibm.com/developerworks/community/blogs/jfp/entry/Installing_XGBoost_For_Anaconda_on_Windows?lang=en

[mingwandroid]

To install the official Anaconda Distribution xgboost Python package please use conda install py-xgboost (on Windows, Linux or macOS), for the R package, it's conda install r-xgboost.
